Restore Your Car’s Electrical System and Get Back on the Road
Are you dealing with baffling electrical problems in your 2006-2013 Chevrolet Impala? Intermittent power windows, flickering dash lights, a security system that acts up, or even a no-start condition can often be traced back to a single, critical component: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it starts to fail, it can cause a cascade of frustrating and unpredictable issues. Instead of facing a costly trip to the dealership for diagnostics and programming, we offer a straightforward, reliable solution.
This is a direct-fit replacement Body Control Module, part number 25934763, that arrives at your door ready to install. We take the hassle out of the repair by performing a professional Cloning Service before we ship. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your car. This ensures seamless integration and restores full functionality, saving you hundreds in dealer fees and programming time.
A Technician’s Notebook: The Case of the Haunted Impala
I remember a 2011 Impala that came into the shop with a list of symptoms that sounded like something out of a ghost story. The radio would change stations on its own, the dome light would stay on, and the driver’s side power window had a mind of its own. The owner had already replaced the window switch and checked the wiring. After connecting my scan tool, I found a series of U-codes (communication errors), specifically a U0140, pointing to a loss of communication with the BCM. These modules, especially on this platform, can suffer from internal circuit board failures that create these bizarre, intermittent electrical gremlins. A new, properly programmed 2006-2013 Impala Body Control Module resolved every single issue, turning a haunted car back into a reliable daily driver.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is illuminated, or the alarm goes off randomly.
- ✔ The engine won’t crank or start, even with a good battery (anti-theft system engaged).
- ✔ Multiple communication error codes stored, such as U0140, U0155, or other U-codes.
- ✔ Unresponsive key fob or remote start functions.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- ✔ Locate the BCM: On the 2006-2013 Impala, the Body Control Module is typically located on the left-hand (driver’s) side of the dashboard, often near the steering column or behind the lower dash panel.
- ✔ Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module. These usually pop off with a trim removal tool or have a few screws holding them in place.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and reconnect all electrical connectors, ensuring they click securely into place.
- ✔ Final Steps: Reinstall the trim panels and reconnect the negative battery terminal. Start the vehicle to verify that the electrical functions have been restored.
Important Post-Installation Information
While our VIN programming makes this a near plug-and-play repair, some vehicle systems may require a relearn or synchronization procedure after the BCM is replaced. This is normal and ensures all related components communicate correctly.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
What does a Body Control Module (BCM) do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, key fob functions, and more. When it fails, you’ll notice these systems behaving erratically.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the replacement BCM with the correct software and vehicle-specific options from GM. This makes the installation process simple and eliminates the need for a trip to the dealership for programming.
Do I need to send you my original BCM?
No, this service does not require you to send us your original part. We program a replacement module for you based on your VIN. Your original module is always returned to you along with the programmed replacement unit. We do not keep the core.
Is this a difficult part to install for a DIYer?
For most DIY enthusiasts with basic tools, this is a manageable job. The main challenge is accessing the module, which is usually located under the dashboard. Since our module comes pre-programmed, the most complex part of the job is already done for you.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional shop with a compatible bi-directional scan tool.
